AP Biology: Lab 5

OVERVIEW In this experiment you will work with seeds that are living but dormant. A seed contains an embryo plant and a food supply surrounded by a seed coat. When the necessary conditions are met, germination occurs and the rate of cellular respiration greatly increases. In this lab you will: 1. Measure oxygen consumption ...continues

Biology and evolution

What are biology and evolution?

Case Study "The Life Around Us"

Identify two different types of organisms that you have seen interacting, such as bees and flowers. Now form a simple hypothesis about this interaction. Use the scientific method and your imagination to design an experiment that tests this hypothesis. Be sure to identify variables and a control for them. Text Book: Biology ...continues

Osmosis, diffussion and cell membrane

I am trying to compare process osmosis and diffussion and how does the two process help a plant leaves remain firm? 2. How exactly does a cell membrane structure related to its function?

Multiple choice

I am trying to double check the answers that you get with the ones that I have. 1) Lactose is a disaccharide of glucose and galactose, and its digestion requires the actions of the enzyme lactase If the lactose is taken in as part of the diet, but not digested by lactase, this sugar is then metabolized by bacteria in the ...continues

A few questions I am interested in finding out more on:

What distinguishes a eukaryotic cell from a prokaryotic cell? Why embryos are an excellent source for stem cells? Why do cows have the ability to breakdown cellulose into glucose and humans can not digest cellulose?

A variety of possible hypotheses are given to explain the possible interactions between a bee and a flower and suggestions are made as to how experiments that involve the control of variables can be used.

Two different types of organisms seen interacting such as a bee and flower form hypothesis using scientific method and imagination and identify variables and control.

Photosynthesis, metabolize energy

What are possible benefits and negative results we might expect if humans were genetically engineered to undergo photosynthesis? how plant and animal cells metabolize energy in complimentary ways?

5 Questions

1. Select a molecule. List the atoms that that molecule is composed of and describe the type of bond that holds those atoms together. Be sure to explain how this bond works. 2. Often, prokaryotic cells exist as simple unicellular organisms, but in some species, prokaryotic cells can grow together in colonies or filaments. In ...continues

The integrity of the plasma membrane is essential for cellular survival...

1. Answer three of the following five questions in a 3-4 page summary. The integrity of the plasma membrane is essential for cellular survival. Could the immune system utilize this fact to destroy foreign cells that have invaded the body? How might cells of the immune system disrupt membranes of foreign cells? (Two hints: virtu ...continues
